Jamie Williams, 29, is charged with a misdemeanor simple assault charge. He said he regrets slapping the 6-year-old boy July 16 at the Kiddie City Child Care Center.

"The child came home with a lot of bruises, busted lip," Williams said. "I kind of lost it for a moment. I hate that I put my hand on a child like that; that was wrong. But at that point in time, I just lost it."

Surveillance video given to the Vicksburg Police Department by the owner of the day care shows a 9-year-old boy punching and biting Williams' 11-month-old son, Jamie, as the baby sat in a highchair. The same 9-year-old was also captured on video forcefully kicking Williams' 2-year-old daughter, Jazzmine, police said.

When Williams arrived at the day care, he asked a group of children how his children were injured, police said. The 9-year-old blamed a 6-year-old boy for the attacks, police said. Williams can be seen on the video walking over to the 6-year-old and slapping him, police said.

Sandra Tevillion, who was working at the day care during the attacks, either didn't see what was happening, or did nothing to prevent it, police said. Tevillion has been charged with two counts of contributing to the neglect of a minor as a result, police said.

Williams said his children are recovering, but his daughter is troubled by what happened.
